The Radio Design Labs D SERIES-TPS8A modules are two-pair audio sending modules compatible with RDL Format-A twisted pair products. These modules are designed to be mounted in wall boxes, cabinets or other enclosures that allow users to connect audio sources. The D- and DS- models mount in RDL WB-1U and WB-2U wall boxes, or in standard U.S. electrical boxes. The D-TPS8A features a white front-panel laminate with gray lettering that matches RDL Decora®-style remote controls. The DS-TPS8A is constructed of stainless steel to coordinate with RDL Decora-style stainless steel remote controls in commercial/industrial installations. The DB-TPS8A features a black front-panel laminate.

The -TPS8A modules feature one stereo Mini jack input on the front panel. The input is designed to receive standard -10 dBV consumer level signals from sources such as a computer or personal media player. The input signals are amplified using studio-quality preamplifiers optimized for normal operating levels. The buffered left and right inputs are routed to output cable pairs B and C. These modules drive only two cable pairs, therefore they accept a signal and power from one mic-level or line-level Format-A single-pair sender. One single-pair sender may be chained with the -TPS8A. A single-pair sender must be set to feed pair A if it is connected together with the -TPS8A.

The -TPS8A modules have a Format-A input on the rear panel. This RJ45 input receives left and right signals from preceding senders and sums them together with the local Mini jack input. This allows multiple –TPS8A modules to be connected in series with all the Mini jack inputs remaining active.

The -TPS8A is remotely powered through the twisted pair cable from any other module, signal distributor or RDL power inserter connected to the same twisted pair cable. There are no illuminated indicators that could be distracting in dark locations, such as a hotel room. RDL FORMAT-A features design simplicity, ease of installation, unsurpassed flexibility, automatic fused power, exceptional hum rejection, low noise, and low distortion to provide installers the optimum choice in economical twisted pair products.
